It's an Intel-powered smartphone running Android Lollipop that's compatible with AT&T and T-Mobile, and other cellular networks that utilize GSM technology, like Straight Talk, MetroPCS, and Cricket Wireless among others.The device is packing a quad-core Intel Atom Z3580 (2.3GHz) with PowerVR G6430 graphics and 4GB of RAM, along with Intel 7262 and Intel 2230 modem tech, a 5.5" Full HD screen, a 13MP rear camera, dual-SIM support and 802.11ac Wi-Fi. The high-end model can be had for only $299, unlocked. A $199 version with 2GB of RAM and a slightly slower Intel Atom Z3560 is also available. In the benchmarks, the Zenfone 2 offers competent though middling performance but considering Asus has priced the ZenFone 2 so aggressively, it's sure to grab some attention at retail with consumers looking for a contract-free commitment.
